Battery Backup – System Memory
The battery on the CD-CP00-US retains the Clock/Calendar and Last Number Redial
(LNR) buffers for each station when the CD-CP00-US encounters a power loss. With
a fully charged battery, the settings are retained for approximately three years.
The system programmed memory (Customer Database) is stored in Nonvolatile
Memory and can be erased only by performing a First Initialization.
Battery Backup – System Power
A built-in battery provides complete system operating power for approximately 30
minutes during commercial power outages. When optional (locally provided) batteries
are connected and fully charged, full system operation can be maintained for an
extended time. Actual time depends on system configuration, traffic conditions, and
the battery capacity.
Call Appearance (CAP) Keys
This feature automatically places an outside call on a Call Appearance key when the
system is operated as a hybrid (Multifunction) system. These keys can be assigned
on any multiline terminal or the same key can appear on multiple terminals. This
feature allows efficient call handling when numerous CO calls are received and a
limited number of CO line key appearances are available.
Once a Call Appearance (CAP) Key call is set up, the user can handle it like any other
trunk call. For example, the user can place the call on hold, transfer it to a co-worker
or send it to a park orbit. An incoming call is answered on the first available CAP key,
beginning with the lowest numbered key. If keys 1~3 are Call Appearance (CAP)
Keys, for example, the first incoming call is answered on key 1. If key 1 is busy, the
next call is answered on key 2. If keys 1 and 2 are busy, the next call is answered on
key 3. If all three keys are busy, additional incoming calls queue for the first available
key.
Call Arrival (CAR) Keys
Call Arrival (CAR) Keys are software extensions available on the Basic and Expanded
Port Packages. A Call Arrival Extension assigned to a line key, can appear and ring
on an individual station or multiple stations. Call Arrival (CAR) Keys are busy only
when in the ringing state and are not used during the talking state.
Call Arrival (CAR) Keys are shared with the Virtual Extensions (VE). In virtual
extension mode, the key acts as a secondary extension. Up to 256 CAR/VE keys are
provided.
2 - 12
For additional storage time, the database and Caller ID History can be copied to the Compact
Flash card on the CD-CP00-US.
